Symmetries and Local Conservation Laws of Variational Schemes for the Surface Plasmon Polaritons
Qiang Chen, Xiaojun Hao, Chuanchuan Wang +3
The relation between symmetries and local conservation laws, known as Noether's theorem, plays an important role in modern theoretical physics. As a discrete analog of the differen…

Variational Schemes and Geometric Simulations for a Hydrodynamic-Electrodynamic Model of Surface Plasmon Polaritons
Qiang Chen, Lifei Geng, Xiang Chen +3
A class of variational schemes for the hydrodynamic-electrodynamic model of lossless free-electron gas in a quasineutral background is developed for high-quality simulations of sur…
